Connecting people. Connecting Communities.

This week’s photos feature above and below ground images at the Union Square|Market Street Station. Here, a backhoe fitted with a jackhammer breaks up pieces of concrete during excavation of the station box.

Below, sparks fly as a worker uses an angle grinder to smooth edges of a steel bracket inside the north concourse, where temporary steel reinforcing is being installed.

An underground view of the southeast corner of the Union Square Garage where construction of the north station entrance is ongoing.

If you would like to see more photos of project construction, check out our Flickr, updated weekly!
